Well, just spent my stimulus money on a Rad ebike. I am sure I will be much stimulated. Maybe even more so if congress approves ebike 30% tax credit. Before the ebike arrives, I am trying to figure out best ways to charge up battery while in the boonies for multiple days.
I have read RC Jim’s post on ebike, watched Utube on charging while camping. Seems like many options exist for me while out there in my FWC, and I like options and I like to explore what seasoned ebike and FWC owners have done.
I do have a Honda eu2200i, and some have posted that they charge the bike just fine, but I am not sure if the inverter on the eu2200i is a pure sine wave type specified by Radbike for charging the lithium 48 v. I do carry a 350 watts pure sine wave inverter on trips that I can use off the camper battery or the generator if needed.
I have 160 watts stock ZAmp plus 100 watts Renogy on top, which is more than I need as the AGM gets topped up by 10 or 11 in the morning. I can get more or bigger panels if needed to charge up to two 750 watts, 48 v batteries. I plan on getting extra ebike battery or built my own to extend range of the ebike. The battery are pretty expensive and I don’t want to ruin them while charging it. The Ideal set up for me is to be able to have two fully charged ebike battery for the days ride, while charging a spare battery during the day with solar and after getting back to camp, be able to top off the two used up battery with either generator or via inverter off camper battery. Double my needs if I bring a friend with Rad ebike too.
Some have used separate batteries and inverter to charge the ebike battery, and I may explore that option too if I DIY a 48v Lithium power center. But that maybe the most expensive option and it will have to wait.
I also saw on Utube ebike owners solar charging directly from panel to Victron mppt controller and plug into ebike battery directly without using the Radbike charger, which lead me think maybe I like a separate charging setup from FWC. So, I hope all the solar and electrical and ebike gurus on the forum can give me some advise on what is the best way to keep on riding.
